Abstract (en)
[origin: WO2019206771A1] A driver arrangement is provided for a LED lighting device with a LED light source and at least one additional auxiliary module. The driver arrangement comprises separate main and auxiliary drivers. The delivery of power from the auxiliary driver is controlled to either an auxiliary power output or to both a main power output and the auxiliary power output. Each driver can be optimized for the load it is required to drive. The device may overall be more efficient in a low power auxiliary mode, by using a driver suited for such low power operation. In particular when the power demand of the LED light source is low, the auxiliary driver may be used.
